The world is Nick Kyrgios' oyster after his sensational Wimbledon victory over world No.1 Rafael Nadal looks set to open the door to million-dollar contracts, says celebrity agent Max Markson.

Markson said Canberra's Kyrgios had received phenomenal exposure through his four-set victory over the 14-time grand slam winner on Wednesday morning, which set up the quarter-final against Canada's Milos Raonic scheduled for overnight.

He has now taken over from the controversial Bernard Tomic as the face of Australian tennis.

The high-profile manager, who lists Bill Clinton, Nelson Mandela and Kim Kardashian as clients, thinks Kyrgios rocketing into the men's top 100 has started him on a path to potential career earnings in excess of $20 million – and that does not include endorsements.

His prizemoney is now about $248,000, but that will almost triple regardless of whether he beats Raonic.

A quarter-finalist gets about $410,000, which jumps to nearly $800,000 if he makes the semis.

Nike and Yonex sponsor Kyrgios, and Markson expected making the Wimbledon quarter-finals would lead to bigger and better contracts with the two sports giants.

"It's fantastic for establishing him,'' Markson said. ''A few weeks ago probably nobody outside the tennis community and sports community knew who he was; now he's got phenomenal exposure for his name.

"From a commercial point of view, he's already in bed with Nike and Yonex, so it'll mean they'll upgrade his [contract].

"He'll be on some sort of incentive to make the top 100 or whatever, so that will become million-dollar contracts."

It will also open the door for many other opportunities following the explosion of Kyrgios' popularity right across the world.

Born in Australia, his father George is Greek and his mother Nill is Malaysian, with fans from all three countries claiming him as their own.

His number of followers on social media site Twitter has increased by 35,000 since the start of Wimbledon, and Markson said sponsorship opportunities would arise across platforms like Facebook and Instagram as well.

It has continued his rapid rise into the public sphere, which saw his personal website nickkyrgios.org crash during the Australian Open in January.

Markson said Kyrgios' manager, John Morris, from Global Tennis Connections, would look to lock in two- or three-year deals, rather than just one-offs.

Watches, sunglasses, phones and breakfast cereals are all possibilities on the horizon.

Morris told The Canberra Times in January they would be selective about endorsements so that they could build a high-end brand similar to Nadal and Roger Federer.
